ALS — Glycine max

Summary

GLYMA_01G070700V4 (GmALS) encodes an acetolactate synthase (ALS) enzyme, also known as acetohydroxyacid synthase (AHAS), which possesses acetolactate synthase and pyruvate decarboxylase activities, binds thiamine pyrophosphate, FAD, and magnesium, and localises to the chloroplast stroma as part of the acetolactate synthase complex. This gene is associated with branched-chain amino acid anabolism, particularly valine anabolism, as well as photorespiration, nitrogen fixation, nodulation, secondary and lipid metabolism, and responses to salt and herbicide. GmALS has been connected to traits including nitrogen content, seed weight, plant height, and salt response. Studies of related genes in other species link the ALS family to herbicide resistance and sensitivity, imidazolinone and sulfonylurea tolerance, enzyme stability, and plant growth and seed production.
